MONEY BOX CONSTRUCTION Filed Oct. 28, 1964 7 Sheets-Sheet 7 INVENTOR.MITCHELL A. HALL Y, -Q-f 240 BY 1 206 202 4, ATTORNEY United StatesPatent 3,276,835 MONEY BOX CONSTRUCTION Mitchell A. Hall, 445 RossfordAve., Fort Thomas, Ky. Filed Oct. 28, 1964. Ser. No. 407,112 28 Claims.(Cl. 312-333) This invention relates to a money box construction, of thetype suited for use in accumulating coins from the coin chutes ofdispensing machines; laundry service machines, coin telephones, andsimilar coin-operated devices. Such money boxes are adapted to be lockedto a rigid frame fixed within the casing of the dispensing or servicemachine, so that removal of the box and contents from the machine casingmay be achieved only by an authorized person in possession of a properkey. Such person may thereby remove a box containing accumulated coins,and substitute therefor an empty box. The box removed will ordinarily beforwarded to a coin-counting oflice.

In some instances, it may be desirable to provide the money box with adetachable lock-unit, so that the box of coins removed from the machinemay be forwarded to the counting oflice with the lock-unit detachedtherefrom. The detached lock-unit may under such circumstances beapplied by the serviceman to the empty replacement box, thereby to avoidthe forwarding of lockunits to the counting ofiice. Such procedure keepsthe lock-units in constant service, and may be of advantage foraccounting purposes.

An object of the present invention is to provide an improved locking andbolting mechanism for money boxes and the like, which effectively defiespilfering even though the attempt may result in severe mutilation ordestruction of the locking mechanism.

Another object of the invention is to provide in a money boxconstruction, a simplified and highly effective means for maintaining abolted affixation of the box to a stationary frame, in defiance ofunauthorized removal by drilling of the lock or other elements of thelock-unit, or by driving the lock from normal position within the unit.

A further object is to provide in a device of the character stated,means for facilitating and expediting the exchanging of lock-units onmoney boxes, and in the alternative, effecting a simple semi-permanentafiixation of the lock-unit to a box.

A still further object of the invention is to provide means in a deviceof the character stated, for the multiple bolting of a door to asupporting frame with maximum ease and ample security.

The foregoing and other objects are attained by the means describedherein and illustrated upon the accompanying drawings, in which:

In the drawings, FIGS. 1 to 4, the numeral 30 indicates a sheet-metalmoney box, having a lid 32 apertured at 34 to receive coins releasedfrom a coin slide (not shown). The lid aperture may be furnished with ahinged closure member 36, which may be closed and sealed when the boxcontaining a quantity of coins is to be separated form its supportingframe 38 and forwarded to a coin counting office. Frame 38 is astationary element fixed securely within the cabinet or housing of adispensing machine or the like.

Coin box 30 carries a lock-unit 40 (FIG, 5), which normally is fixed tothe box, but which may quickly be detached therefrom after the unit isunlocked from frame 38 to penmit withdrawal of the box from frameaperture 42. Detaching the lock-unit by the Serviceman enables him toapply the same lock-unit to an empty replacement box which replaces theone removed. The box removed may therefore be transported to the coincounting otfice, relieved of the weight and bulk of the lock-unit.

The lock-unit may comprise a flat door or front plate 44, and apermanently mounted boltwork housing 46 which may be welded or otherwisesecured to the rear face of the door. A lock case 48 fixed to housing46,

, extends through a central aperture of door plate 44 and mayaccommodate a key 50 for extending and retracting the multiple bolts 52.The bolts may be projected through upper, lower and side openings 54 ofhousing 46, to engage a hard steel flange 56 applied to frame 38marginally of aperture 42, for bolting the lock-unit and accompanyingcoin box to the frame.

of one or more springs.

FIGS. ,5, 6, and 7, show the lock-unit separated from the coin box, bymeans of a quick-detachable connection. As shown, lock-unit, or boltworkhousing 46 is provided with pairs of fixed lugs 58, which extendinwardly from opposite sides of the housing. The lugs are engageable bydepending hooks 60 carried by the coin box, so that the box normallyhangs on the lugs. To effect a connection, it is necessary only toinsert the lugs 58 of the bolt housing behind the hooks 60 of the coinbox, so that the box hangs from the lugs. Detachment involves liftingthe box sufficiently .to disengage the books from the lugs, and thenmoving the box away from the lockunit-as in FIG. 5.

To avoid inadvertent separation of the coin box from the lock-unit, thebox may be provided with a leaf spring latch 62 having a hooked end 64to engage an upper lug 58 upon assembly of the look-unit upon the .box.

The spring latch may be accessible through an opening 66 in one side ofthe box, so as to be manually flexed for disengaging the hooked end 64from upper lug58,

thereby to free the lock-unit for detachment from the coin.

holes 70 incident to detachment of the lock-unit from the box. Thepimples 68 and holes 70 constitute friction detents which are readilyseparable.

In the event that a semi-permanent connection between the lock-unit andcoin box is desired, a screw 72 may be inserted through an opening 74 inthe -bolt housing, to engage a threaded hole 76 in hook flange 78.Removal of the screw permits detachment of the lock-unit from the coinbox. Screws such as 72 may be applied at opposite sides of boltworkhousing 46.-

The reference numeral 80 indicates a laterally swingable latch to engagebeneath the upper flange 82 of boltwork housing 46, to hold lid 32 inclosed position while the coin box is attached to the lock-unit. Thefront wall 84 of the coin box may be provided with a depression 86 toaccommodate the inner end portion of lock 48, if necessary. Front wall84 is a permanent element of the coin box, applied in any suitablemanner; and lid 32 may or may not be hinged upon the box, as desired. Aseparable hinge is shown at 88-90, FIGS. 6 and 21.

The details of the boltwork are illustrated by FIGS. 9 to 13, inclusive,wherein the numeral 52 indicates a plurality of bolts which may beextended through slots 54 in boltwork housing 46, to engage the flange56 of frame 38 serving as a keeper. Bolts 52 may be in the form ofprotuberances fashioned on a pair of bolt plates 94 and 96, hinged at 98and 100 upon housing 46. Each bolt plate may be in the shape of a bellcrank as shown in FIGS. 11 and 12, and the divergent arms of each bellcrank may carry one or more bolts 52. Each arm carries two bolts in theexample illustrated.

Referring to FIGS. 11 and 12, it is apparent that slight movement of abolt plate in one direction about its pivot 98 or 100, may extend thebolts 52 through slots 54 as in FIG. 11, to lock the boltwork housing 46relative to flange or keeper 56. Conversely, movement of a 'bolt platein the opposite direction about its pivot will vretract the bolts, as inFIG. 12, so they will clear the keeper and thereby permit withdrawal ofvthe coin box from the frame aperture 42, according to FIG. 2.

Bolt plates 94 and 96 are constantly yieldingly urged outwardly toextend their bolts 52, preferably by means Inthe example illustrated, asingle spring 102 is employed, operative to extend both bolt plates 94and 96. Spring 102' may be in the form of a resilient arched wire havingopposite ends thereof box.

4 impinging against lugs 104 formed on the bolt plates, to constantlyyieldingly urge the plates in opposite directions about their respectivepivots 98 and 100.

Key lock 48 has a central shaft 106 to which is fixed, as by means of anut 108, a yoke 110 which includes a pair of legs having slots 112formed in the free ends thereof. The slots are loosely receptive of apair of lugs 114 which extend from one face of a flat cam disc 116,which disc is centrally apertured at 118 for rotation about a hub 120.The hub concentrically surrounds the threaded lock barrel 122,. and maybe fixed to the barrel by means of a nut 124 and washer 126. Thus,whenever the lock shaft 106 is rotated by means of a proper key 50, yoke110 will drive the cam disc 116 by reason of the connection 112-114.

Cam disc 116 has formed therein a pair of spiral cam slots or tracks130, and each track slidingly accommodates a follower 132, saidfollowers being in the form of lugs formed integrally upon the boltplates 94 and 96. Thus, rotation of the cam disc enforces movement offollowers 132,132, toward and from shaft 106, to

retract and extend bolt plates 94 and 96, and their several bolts 52. a

The gradual long slope and short throw of cam tracks 130, ensures easymanipulation of the door bolts by means of key 50. Noteworthy also isthe fact that follower lugs 132 engage the cam tracks at right angles tothe plane of the cam disc 116, and will therefore readily leave thetracks in the event that a thief drives the lock forcibly through door44 in attempting to gain access to the coin Displacement of the lock andcam disc 116 rearwardly, will result in freeing the followers 132 fromthe cam disc, whereupon spring 102 will effectively maintain an extendedor operative condition of all the bolts 52. Also, if driving of the lockdisplaces yoke 110 to destroy .the connections at lugs 114, cam plate116 will be immobilized in the bolted condition of the door. The spring102 insures, further, a bolted condition of the door even though thethief may resort to drilling the door or the lock in various ways. Notealso that bolting occurs all around the perimeter of the door, or alongfour sides thereof.

It may here be noted that with only slight modification, the lock andboltwork above described may be applied to doors which are circular,rather than rectangular, while preserving all the advantages abovereferred to. In the case of a circular door construction, the coin boxmay be either rectangular or cylindrical in shape, with correspondingmodification of the shape of frame aperture 42.

FIGS. 14 to 24, inclusive, illustrate a modification of the boltwork,and of the means employed to mount and demount a lock-unit relative to acoin box. The coin box in this instance has an opening 136 in the rearwall thereof, aligned with an internally threaded nut 138 carried by aportion 140 of frame 38, for reception of an elongate threaded bolt (notshown), which normally ties the box to the frame. This constitutes oldpractice which forms no part of the present invention, and shouldtherefore be ignored as the tie mentioned will not be used inconjunction with the present invention.

The sheet metal box, FIG. 15, carries a pair of forwardly extendedarcuate arms or wings 142, which may be formed integrally with the boxsides. The armsare capable of slight outward flexion to the extent ofthe in-. herent resiliency of the metal sides. Said arms are adaptedtosnap over and embrace a pair of spaced parallel posts 144 on lock-unit40, FIGS. 22, 23, 24, for detachably mounting the lock-unit by means ofrearwardly extending lugs 146 struck from a bolt housing plate element148 (FIG. 16) which element 148 may be spotwelded against the back ofdoor 44. The same posts 144 are adapted to pass through perforated lugs150 of a second housing plate member 152,;for supporting the latter inspaced parallelism with plate member 148. The

space between members 148 and 152 accommodates the bold elements 154 forextensile and retractile movement about pivots 156, 156.

The upper pair of lugs 150 may be provided with depending hooks 158 toengage the upper edge of box front 84, so that the lock-unit may hangfrom the box. The box lid may be cut away at 160, 160, to permitengagement of books 158 with the upper edge of the box front wall. Thelower lugs 150 need not carry hooks such as 158. FIGS. 22 and 23indicated how the lockunit may be applied to and detached from box 30,by tilting one part relative to the other. FIG. 24 shows the arms 142yieldingly embracing the posts 144 to hold the parts in the FIG. 22position.

Referring to FIGS. 16, 17 and 18, it is noted that lock 48 comprises anexternally threaded body 162, and a shaft 164 which may be rotated uponinsertion of a proper key into the lock. Lock body 162 fits snuglywithin an aperture 166 of plate 148, and extends also through a centralaperture 168 of plate 152. Plates 148 and 152 may be spaced apart by awasher 170, which maintains clearance for movement of bolt members -154,154 between the plates. The bolt members may be of hell crank formationas shown, with holes 172 provided for pivotal connection with pivotmembers 156.

Corresponding arms 174, 174 of the bolt members carry lugs 176, 176which extend in a common direction at right angles to the bolt members.These lugs are cam followers, which extend through apertures 178 inplate 152 to engage cam slots or tracks 180 of a cam disc 182. Thecentral bearing 184 of the cam disc rides upon hub 186, and a nut 188threaded onto the lock body holds the cam disc in place upon the hub.

To the outer end of lock shaft 164 is fixed a cap 190, secured by meansof a nut 192. The cap has a driving connection with cam disc 182,consisting of an outstanding lug 194 on the disc loosely received in anotch 196 of the cap, whereby rotation of lock shaft 164 and cap 190 isimparted to the cam disc. It will be understood that rotation of the camdisc by shaft 164, with followers 176 riding in cam slots 180, enforcesmovement of bolt members 154 about their pivots 156, to extend andretract the bolt members into and from locking engagement with theflange 56 of frame 38, FIG. 14. Both legs of each bolt member may engageflange 56 when the bolt members are extended (FIG. 18).

With reference to FIG. 15, the coin box wall 84 is recessed at 86 toaccommodate cap 190. Should a thief drive the lock through door 44 andthereby displace cap 190 away from cam disc 182, the connection at194196 would be broken so as to prevent any subsequent rotation of thecam disc, and consequently, prevent withdrawal or retraction of the boltmembers from operative position. The bolt members may be spring-loadedas suggested at 199, to urge the bolt members constantly toward lockingposition.

It will be apparent by referring to FIGS. 16, 17, 18, that drilling thedoor or the lock in an attempt to gain access to the coin box, cannotsuccessfully be accomplished. Neither will destruction of the lockafford any advantage in the attempt to pilfer the coin box. In FIG. 14,the reference numeral 198 denotes a flanged aperture of frame 38,through which coins may be guided from one or more coin slides to thecoin box aperture 34. Suitable coin slides may be supported by the upperapertured portion of frame 38.

In the modification, FIGS. 25, 26, 27, the housing 200 for bolt members202, 202, is welded or otherwise fixed to the back of door 44, and hastop and bottom flanges 204 and 206 flanked by opposed side flanges 208which may be integral with a back wall 210. The side flanges and thebottom flange may carry inwardly directed hooked lugs 212, to engageslots 214 of the coin box walls in detachably mounting the lock-unitupon the coin box. As FIG. 27 clearly indicates, the sides of the coinbox may be flexed inwardly, as at 216, to facilitate attach ment anddetachment of the lock-unit.

locking connection one with the other The top and bottom flanges of theboltwork housing may be provided with elongate slots 218, through whichthe bolting portions of the bolt member 202 may be extended andretracted. The bolt members in this instance are' bodily slidable inopposite directions within a common plane, while resting flatwiseagainst the back Wall 210 of the housing. The door and the back wall areapertured as at 220 to accommodate the threaded body 222 of lock 48, anda nut 224 engaging the threads of the lock body holds the lock in fixedposition thereon. The bolt members may be recessed at 226 to avoidinterference with nut 224 as the bolt members retract.

The lock has the usual shaft 228 to be rotated upon insertion of aproper key into the lock, and upon the end of the shaft is secured a camdisc 230, preferably by means of a nut 232. The cam disc may be providedwith an extended hub 234 centrally apertured to receive lock shaft 228,and about the hub may be located the spiral cam slots or tracks 236..

The spiral cam slots or tracks 236 loosely receive the extendingfollowers or studs 240 which are fixedly secured to the bolt members, sothat rotation of the cam disc in opposite directions by means of a keyinserted in lock 48, will serve to extend and retract the bolt membersthrough the slots 218 of housing 200. FIG. 26 shows the bolt members 202fully retracted (full lines), whereas the broken lines 242 shows thebolt members extended so as to engage a flange 56 of frame 38. The twobolt members, if desired, may be spring-urged toward the locking orextended position, as suggested in the description of FIG. 11.

In all forms of the device herein disclosed, the lockunits for the coinboxes may be separated from the boxes with great ease and dispatch, andre-assembly is just as readily achieved. The ability to gather coinboxes from the machines which they serve, and to convey or forward thecoin boxes without lock-units attached, is of great advantage. Theweight of the shipment is thereby substantially reduced, and a minimalnumber of lock-units is needed since all the lock-units on any givenservice route are kept in constant use.

The lock-units per se incorporate several important improvements, whichas previously explained, greatly enhance ease of bolt manipulation, andpromote maximum security against pilfering of the coin boxes. Theassembly of box and lock-unit eliminates accessibility of partsvulnerable to removal or disassembly, and precautionary measures areemployed to foil any attempts to gain access to the coin receptacle bydrilling the lock or the door front, or by driving the lock from thedoor of the receptacle. The door in each embodiment of the invention maybe constructed of tough stainless steel if desired, and tough steel maybe employed in constructing other vital elements of the assembly.

It is to be'understood that various modifications and changes may bemade in the structural details of the device, wit-hin the scope of theappended claims, without departing from the spirit of the invention.
